    * mcalib/MCalibrationChargeCalc.[h,cc]
      - added MCalibrationQECam
+
+   * mcalib/MCalibrationChargePix.[h,cc]
+     - took out fNumLoGainSampels whihc is not needed any more because 
+       conversion is only done in the getters
+     - Canceled function ApplyLoGainConversion (for same reason)
